    The <span class="function"><strong>cubrid_num_rows()</strong></span> function is used to get the
    number of rows from the query result.  You can use it only when the query
    executed is a select statement.  When you want to know such value for
    INSERT, UPDATE, or DELETE query, you have to use the
    <span class="function"><a href="function.cubrid-affected-rows.html" class="function">cubrid_affected_rows()</a></span> function.
  </p>
  <p class="para">
   Note: The <span class="function"><strong>cubrid_num_rows()</strong></span> function can only be used
   for synchronous query; it returns 0 when it is used for asynchronous query.
